Normally, I do nothing at night, except watching random videos on YouTube. Tonight, I discovered a South Korean girl group called Wonder Girls.

They are a huge success in South Korean. In 2009, they entered the North American market with the leading single “No Body”. In Oct 2009, the song made a debut on the Billboard Hot 100. It becomes the first Korean group to enter the chart.

Enough talk, so let’s look at their live performance in So You Think You Can Dance.

The song is very popular and catchy, then many people start to copy them. That is where things become hilarious.
